Ignition vs Karbon

Both Ignition and Karbon sit in AI Practice Management, and firms regularly shortlist them together. They are not interchangeable: Ignition is aimed at firms fixing their billing process, while Karbon is built for growing accounting firms. Ignition does not publish a public price, and Karbon does not publish a public price.

Choose Ignition if

• You need firms fixing their billing process
• Proposal through to payment in one flow
• Reduces debtor days materially

Choose Karbon if

• You need growing accounting firms
• Email and workflow genuinely unified
• Good visibility of who is waiting on what

What to watch either way

• Ignition: Not a workflow tool
• Karbon: Per-user cost adds up
